Mesoamerican warfare used loose formations with space between warriors, allowing cavalry horses to break through.

“at a distance and break up the impetus of their charge but that requires one the technology and two the discipline training and institutional knowledge to do that mesoamerican warfare was very loose in its formation warriors would want a lot of space between them which is the worst thing that you can do in regards to cavalry because the horses can take advantage of that looseness to just blast through any formation that is coming at them”
